CommandImplementations for BoxCommand & ContextualCommand

Until MDAKit 3.0.5 there were available classes named DefaultModuleContextualCommand & DefaultBoxCommand that we could extend and create command classes. But in New MDAKit (3.0.5 onwards) like MDAKit 3.0, these classes have been removed. But no documentation is updated in API Documentation. Still in Documentation it is mentioned to use DefaultModuleContextualCommand to create commands, but unfortunately these classes are not available in JAR>
